Title: Surface plots
Post by: ams_nanolab on July 17, 2016, 14:28

Will ATK 2016 have 3D surface plots for bandstructures? Like ones used to show the mexican hat in graphene?

You can do already today with a few lines of Python code. I'm not familiar with the specific plot you refer to, if you have an example?

Something like this.

This tutorial has an example of how to do Fermi surface plot in 2D: http://docs.quantumwise.com/tutorials/topological_insulator_bi2se3.html#fermi-surface-and-spin-directions (http://docs.quantumwise.com/tutorials/topological_insulator_bi2se3.html#fermi-surface-and-spin-directions). You essentially just need to extract the band energies for the eigenstate on the Dirac cone, and then plot those energies wrt. k-points.
